It easy to use. It ensure us the product is grounded

I bought this to test the concrete around my house and my grounding sheet. It works. Now I know that when it rains I can sit on the patio and still ground.

The green light flashes, which according to the instructions means it’s operable. When I place it on any grounding item or attach a cord which is in the ground outside and press the button for the 3 seconds, the light never comes on. This would mean nothing I’ve tested is grounded = It doesn’t work. Such a disappointment.

Product is not as advertised. Product is very small and flimsy, its like a toy. I wouldnt even want it for free. The advertised product is all white, with a WHITE earthing cord. But I received a thick, chunky BLACK earthing cord instead of a white one as was advertised. It was poorly packaged, wrapped in bubble wrap and put in a zip lock bag, etc. I called Amazon and requested a refund.

This little tester takes the guess work out of the grounding product. Plug it into a grounding plug & press. If the light blinks, the tester is working. Then place it on your connected grounding mat & press the button again. If the mat is grounded, the light will come on&stay on till removing the tester off the grounding mat or pillow case or whatever grounding source you are using.

works fine

It works

Works great for grounding locations

My earthing products have no lights or indicators so it is nice to be able to periodically make sure they are in good working order with this tester.

I was so excited to test my grounding mat, but this tester won’t work. Not sure why but returning it with disappointment.
